摘要

This paper describes a preliminary investigation of predicting jitter of the laser beam at the target when projected from an airborne platform moving through the turbulent atmosphere. The beam jitter is computed by propagating a laser beam through a Kolmogorov simulated atmosphere for various C~2_n values over a 5 [km] range, directed from the platform at 90° off the flight direction. The significance of this study over previous approaches is that actual tracking scenarios are replicated and the results are compared with the literature. It was found that the jitter imposed by the atmosphere is significant and low bandwidth compensation rates in adaptive optics system components such as fast steering mirrors, can make the resultant "corrected" signal worse. The results place new tracking performance limitations on airborne laser systems.
